I’m currently in the proces of customising a VESC 6 design for usage in a robot. The idea is to create a Dual VESC eventually. But first I would like to design a single Vesc to test.
Maximum motor current will be around 20 amps and 10 amps continuous. I’ve left out the NRF24L01P and MPU9150 since we won’t be needing those. Eventually all communication will go over CAN, but for now I left the ppm(or pwm) input for testing purposes.
Below you’ll find the schematics. I’ve designed the PCB as a two layer pcb and made the design in Eagle, if there is any interest the brd and sch can be shared.
Could the more advanced designers take a good look and let me know if there are any weaknesses or point of attention in the design?
Yes it’s a self driving robot, the Vesc will be used to control overboard wheels ~350watt.
And the used mosfets are: NVMFS5C604NLAFT1G since they have more than enough current capability while still remaining quite small, and are easier to solder than the direct fets.
As someone who first stated using VESCs on robots(then esk8), I wonder what is the reason for making your custom VESC: reduce cost, gain design experience(& hence potential for improvements), improved specs?
